D′′ shear velocity heterogeneity, anisotropy and discontinuity structure beneath the Caribbean and Central America
The D′′ region in the lowermost mantle beneath the Caribbean and Central America is investigated using shear waves from South American earthquakes recorded by seismic stations in North America. We present a large-scale, composite study of volumetric shear velocity heterogeneity, anisotropy, and the possible presence of a D′′ discontinuity in the region. Our data set includes: 328 S(Sdiff )-SKS ...
متن کاملCrust and upper mantle discontinuity structure beneath eastern North America
[1] Crust and mantle discontinuities across the eastern margin of the North American craton were imaged using P to S converted phase receiver functions recorded by the Missouri to Massachusetts Broadband Seismometer Experiment. Crustal structure constrained by modeling Moho conversions and reverberations shows a variation of Moho depth from a minimum of 30 km near the Atlantic coast to depths o...
متن کاملMantle shear-wave velocity structure beneath the Hawaiian hot spot.
Defining the mantle structure that lies beneath hot spots is important for revealing their depth of origin. Three-dimensional images of shear-wave velocity beneath the Hawaiian Islands, obtained from a network of sea-floor and land seismometers, show an upper-mantle low-velocity anomaly that is elongated in the direction of the island chain and surrounded by a parabola-shaped high-velocity anom...
متن کاملInvestigating the S Wave Velocity Structure Beneath Southwest North America through Seismogram Comparison of C052297B Earthquake
In this research the investigation concerning the earth structure beneath the Southwest North America landmass is carried out, which covers a small area, i.e. between Mexico and California. S speed models for this area are obtained by carrying out seismogram fitting in time domain and three simultaneous Cartesian components. Seismogram data are the effect of earthquake C052297B in Guererro, Mex...
متن کاملDepth variations of P-wave azimuthal anisotropy beneath Mainland China
A high-resolution model of P-wave anisotropic tomography beneath Mainland China and surrounding regions is determined using a large number of arrival-time data recorded by the China seismic network, the International Seismological Centre (ISC) and temporary seismic arrays deployed on the Tibetan Plateau. Our results provide important new insights into the subducted Indian plate and mantle dynam...
